Cessna 340 RAM VII with 4-blade MT-Propeller
The folks at MT in DeLand do what they say they will.

I've had my MT 4-blade props on my RAM VII 340 for a week now, with about 15 hours in the air.
Firstly, the folks at MT in DeLand do what they say they will. I had a great experience working with them from start to finish, though it did take quite a while for the props to come in. Peter Marshall was who I dealt with and he was a straight-shooter and very responsive. Juergen, their chief tech guy, is all business and really knows what he is doing (but don't expect to have any laughs with him...he's just too busy to laugh ;-)).
The props replaced my Hartzell Scimitars that came with my RAM VII upgrade in 2013 (which are for sale still and have 450 hours on them since new - if interested, let me know). I replaced the Hartzells mostly because I had a tax reason that made sense, and secondly because I've been trying to chase every bit of vibration out of my plane for about a year now.
The MT props have removed pretty much every last bit of vibration, as hoped. They are wonderfully smooth. And certainly much quieter.
At mid-teen altitudes I am now getting 200 kts TAS, about a 5kt improvement. At FL180-220 I've seen 205-208 pretty consistently, where I used to see 203 or so. Summer conditions with freezing level around 14-15,000', and 69% power settings (2300 rpm, 29.5", and 17.2 GPH).
I picked up nearly 40lbs of useful load, too. However, I have not seen any significant increase in climb performance between the Hartzells and the MTs - I know others have remarked that they got a lot better climb rate when swapping from other prop types, though.
The last remarkable difference is, as others have reported, at landing. Wow!!! I can't believe how quick the plane slows up when the power is reduced over the threshold. It is a very nice thing to have, but also requires re-thinking some approach procedures, and not reducing power much below 20-21" until at the threshold. I've been carrying 120kts down glideslope, and aim for about 95kts at the numbers. This requires slightly modified power settings with the MTs vs the Hartzells. But when you are ready to drop it on, you pull the power and the plane feels like a big chute has been thrown out back. Very easy to get it stopped, even on the smallest of strips.
So, guess you could say I'm an MT fan. They do everything I hoped they would, and I'd recommend them and the folks in DeLand.
